FIELD: engines and pumps.SUBSTANCE: additionally, DC source outlet voltage is measured. Measured magnitude is used to define by preset relationship the variable voltage duty ratio that can sustain control signal in gas turbine fuel system. Selected duty factor value is set at pulse supply source output to changeover, in preset time required fro solenoid valve operation, the supply of both windings of two-winding solenoid valve from DC source to that of pulse source.EFFECT: higher quality of ACS, engine reliability and aircraft safety.1 dwg |
